Chinatown:
San Francisco's Chinatown is the oldest Chinatown in North America and is one of the largest Chinese communities outside Asia. Popularly known as a "city-within-a-city", it has developed its own government, traditions, over 300 restaurants, and as many shops. There are two hospitals, numerous parks and squares, a post office and other infrastructure. Visitors easily become immersed in a microcosmic Asian world, filled with herbal shops, temples, pagoda roofs and dragon parades. In addition to it being a starting point and home for thousands of Chinese immigrants, it is also a major tourist attraction — drawing more visitors annually to the neighborhood than the Golden Gate Bridge.
Fisherman's Wharf:
Fisherman's Wharf is a great place to see amazing street entertainers, watch sea lions, visit museums, or take a cruise to the infamous Alcatraz Prison or the pleasant Angel Island. Working fishing boats still come into the small harbor here, and the district is home to several excellent seafood restaurants. The fresh breeze from the bay can provide a bracing setting.
Golden Gate Bridge:
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, it connects the city of San Francisco on the northern tip of the San Francisco Peninsula to Marin County. The Golden Gate Bridge was the longest suspension bridge span in the world when it was completed during the year 1937, and has become one of the most internationally recognized symbols of San Francisco, California, and of the United States. In 1999, it was ranked fifth on the List of America's Favorite Architecture.
Twin Peaks:
The Twin Peaks are two hills with an elevation of about 922 feet (281 m) situated at the geographic center of San Francisco,California. They form the second highest point in San Francisco, after Mount Davidson. The Peaks are often visited by a number of tourists due to the amazing view of the city they offer. The two peaks have a north-south orientation and are divided by Twin Peaks Boulevard, which is the only road leading up to the summit. Twin Peaks also form a prominent divider for the summer coastal fog pushed in from the Pacific Ocean. Due to this unique geographical condition, their west-facing slopes generally receive substantial fog and strong winds, while the east-facing slopes usually receive more sun and warmth.
